For you have died

As Christ actually died, so God counts the Colossian believers as having died with Christ.

your life is hidden with Christ in God

Possible meanings are 1) "it is as though God has taken your life and concealed it with Christ in God's presence" or 2) "only God knows what your true life really is, and he will reveal it when he reveals Christ"
